Synopsis Spanish, Evergreen, and Madrid sweetclovers differed little in dry matter production and nitrogen content in first‐ and early second‐year growth and exceeded common white only in first‐year growth. Hubam produced more forage, but contained no more nitrogen per acre. The biennial varieties did not differ appreciably in quantity of roots per acre. Nearly 90% of the roots were in the top foot. Nitrogen content of the roots decreased with increasing depth.
